QUEREX – OAK BARK EXTRACT 30ml

Tropical Querex is an oak bark extract used to create water conditions that facilitate breeding and spawning of ornamental fish.

It adds natural tannins to the water—organic chemical compounds classified as tanning agents—to create living conditions similar to those in which blackwater fish live.

It encourages fish to reproduce.

Hatching and survival rates of fish are also increased.

It accelerates the regeneration of fish skin, mucous layer, and fins.

It reduces fish rubbing against equipment or decorative elements.

Dosage: 10 ml / 100 liters of water, or until the water reaches the desired color. Use after every full or partial water change, after transport, and during fish acclimation to new conditions, especially when fish are particularly susceptible to skin abrasions and cuts.

Note: QUEREX does not work in hard water. Use in soft and slightly acidic water.
